AMy inventinn relates to ovens. I

Among the objects of invention are To provide an' oven with Va plurality .of metallic pipes forming'lues and `to combine with the oven walls a plurality of structural steel members located and arranged vto support the ends of said' l'lues.

To provide structural'steel members located and arranged to support oven flues and to combine with Saidvreembers a elastic heat resisting material and a plate for shielding said material.

These vand 'further objects'of my invention will be set forth in thev following specification, reference being had to the accompanying drawings, and themeans by which said objects are efectuated will be definitely pointed out in the claims.

In the drawings Figure 1 is a longitudinal section of an oven constructed according to my invention. Fig. 2 is a partial section along the line 2 2 in Fig. 1 looking in the direction of the arrows.

Fig. 3 is a section along the-line 3 3 in Fig. 1 looking in the direction of the arrows. The drawings show an oven having one re box and one set of fines connected therewith, but since the ues in a large oven having many Iireboxes are counterparts of those shown, I shall describe my invention with reference to but a single fire box and the lines connected thereto.

5 represents the fire box which may be formed in any approved manner, provided with a grate of any approved type and having a fire door (not shown), to permit the introduction of fuel therein. The lire box 5 is connected by the horizontal longitudinal fiues 6 6 with the horizontal transverse flue i 7 and the latter is connected to the horizon-- tal longitudinal l'iues 8 8. The :dues 8 8 connect with the vertical flue v9 and the latter 4connects with the horizontal vtransversati@ 110- Y llhelliue 10 is formed by the front wall 11the -tile'fcap plate 12, the flue pipe suppe'rt 13,`the tlnepipes 1a vand the filling 15 aber@ and between same. A

v'heiiue 10 is connected the flue pipes 60 l with the `sont chaniberkl and the latter is connected by the longitudinal approxif mately horizontal lines 17 with the horizontal transverse fine 18, the latter communicatine threueh the' passage 19 with the @him-65 L neyv20v.` The passage 19 may be provided with a .damper 21.

The rear ends of the flue pipes 14 rest upon thewall ,22v and the fr'ontends of said pipes 'rest upon the-'support 13. The support 70 1B is vcomposed ofy a plurality of I beams 3l' v or beanisof other suitable cross section having their ends ksupported bythe vertical longitudinal walls 23--23 and a plate 24 is also supported by safdwalls in contact witb the battere of Said beams! .i

The space 'between thebeams and between the first beam and the front-wall 11 is filled with plastic fire-proof material 25 such as cement or other suitable material.

The baking chamber 26 is formed by the hearth. 27, wall 22, flue pipes lll and plate 24, and the front wall is provided with the 1 opening 28 providing access .to said cham'- ber. The front wall is also provided with clean out holes 29 and 30 to provide accessv to the flues 10 and 18, respectively.

`It is to be noted that by arranging the flue pipes 14C .immediately over the baking chamber 26, I provide `for the most economical use of the heat. Also that by support-v ing the lue pipes 14 upon'the wall 22 and upon the support 13, I provide an exceedingly strong construction for the' support of the pipes 14 and the illing 15. l, 95

It is also to be noted that the supportl,` by reason of the use ofthe plate 24, the I beams 31 and the plastic filling 25, forms substantially a unitary structure having great strength; also that the plate'24 serves l100 to hold the plastic material in place while it is hardening.

While I have shown one vpreferred ar rangement of my improved oven, it is to be understood that this is for purposes of illustration only and in no wise to limit my invention to the exact elements, combinations oi1 elements and arrangement thereof shown, for changes may be made therein Without departingfrom the spirit of my invention.

l claim l. An oven comprising a tire box, a chimney, a hearth, front, rear and side Walls, a fiue pipe support extending from side Wall to side wall and consisting of beams having their ends supported in said side Walls, a plate beneath said beams and plastic Inaterial between said beams and resting upon said plate, iiue pipes supported at one end said rear Wall and at the other by said support, a connection from said fire box to one` end of each of said pipes and a connection from the other end of each of said pipes to said chimney.

2. An oyen comprising a tire box, a chimney, a hearth, front, rear and side Walls, a flue pipe support Dxtending from side Wall to side Wall and consisting of beams having' their lends supported in said side Walls, a plate beneath said beams supported by said side `and front Walls, and plastic material between said beams and resting upon said plate, flue pipes supported at one end by said rear Wall and at the other by said support, a connection from said fire box to one end of each of said pipes and a connection from the other end of each of said pipes Lo said chimney.

f5. An oven comprising a re box, a chimney, a hearth, front, rear and side Walls, a

flue pipe support extending from side Wallto side Wall and consisting of beams having their ends supported in said side Walls, a

rear and side Walls and flue'pipes each sup-r ported at one end by said rear Wall, of a support for the other ends of said pipes consisting of beams having their ends supported by said side Walls, a plate beneath said beams .and plastic material between said beams and resting uponsaid plate.

5. In an oven the combination with front, rear and sidewalls and fiue pipes each supportedl at one end by said rear Wall, of a support for the other ends of said pipesconsisting of beams having their ends supported by said side `Walls, a plate beneath i said beams supported by said front and side Walls, and plastic material between said front Wall and the adjacent beam and between said beams and resting upon said plate.
